Abstract:
In this paper,performance of decompression and low coated gas chromatographic column of non-polar liquid phases is described. Chromatographic parameters of a column packed with 0.5% OV-101 on glazing support (φ0.18～0.25mm) 302 was studied for C、C7、C8、C9 n-alkanes samples. The results showed that the column pressure 0.068 MPa was best,the column temperature for n-octane could be decreased to 52°C,column efficiency was four time as high as ordinary pressure detection.
